The space savings you would get with a regular power supply would be minimal considering that you need a place to put your filament spool. I would have loved to see a “power brick” like you get with a laptop but this would have probably raised the price.Īll things considered, it’s not that bad because you could have the spool holder on top of the power supply. The fan is thermally controlled so it’s powering on from time to time. This is a regular 24V 360W no-name power supply which is present on other cheap 3D printers. While the Kingroon KP3S is a compact machine, some extra space is needed for the power supply. If you don’t print too fast, this can be fine, but adding a radial fan will allow you to have much better overhangs, supports will be removed easier and you will save your sanity if you keep the printer in the same room. It’s not capable of pushing too much air to cool the printed model and it produces a lot of noise. Instead of a radial fan, the Kingroon KP3S uses a regular 3010 fan which is not the right tool for this job. ![]() It’s the noisiest heatbreak fan I heard on all of my printers and the part cooling fan is the same. Unfortunately, this fan is extremely noisy. To cool the heat break, a V6-like heatsink is mounted and a 3010 fan blows cool air over it. It uses V6 nozzles in a somewhat similar heatblock. ![]() It uses an MK8 thread which connects it directly to the metal extruder. The hotend is something I haven’t seen before. Besides that, you also get a more accurate extrusion and better performance when printing flexible filaments like TPU. #Cetus3d problems upgradeIf you’re into modding your printer, you could upgrade to a BMG Wind which will make the whole direct drive setup lighter. It’s not a geared extruder so it might be a bit less accurate compared to a BMG but it works well enough for good quality prints. The direct drive extruder present on the Kingroon KP3S is comprised of a regular NEMA17 stepper motor and a metal extruder, just as the ones found on Creality printers. This will require a bit of modification, but it will ensure a much longer life for the board by decreasing the load on that barrel connector. The best way to mitigate this issue and make sure that no damage occurs for the board is adding a mosfet to power the bed. The heatbed is the most power-hungry component on this printer and I don’t think that the barrel connector is rated for too much power draw. ![]() ![]() Unfortunately, I think that the main drawback of this board is the power connector. #Cetus3d problems driversIt has removable stepper drivers which allow you to easily swap them if one of them gets damaged over time. 32-bit board with TMC2225 driversĪnother welcome addition to the Kingroon KP3S is the 32-bit board which uses TMC2225 drivers. I don’t think potential buyers wouldn’t pay an extra ~10$ to have a 3D printer with linear rails on all axes. I would have liked to see a 3rd linear rail for the Z axis for a complete package, but I can’t say that the regular wheels do a bad job. You won’t be able to push this printer too much without influencing the print quality. In theory, adding the linear rails gives the printer more accurate movements and it should also be able to print faster but it’s held back by the cantilever setup and the direct drive extruder weight. Considering that the Kingroon KP3S is a compact budget machine, it’s really nice to see it equipped with linear rails for the X and Y axis. ![]()
